HOSPITAL PAD 0B, CUSHION.

Application filed June 8, 1921. Serial No. 475,899.

To all whom it may concern:

Be it known that 1., Man DORRANOE, a citizen of the United States of America, and resident of Smithficld, county of Jefferson, and State of Ghio, have invented certain new and useful improvements in Hospital Pads or Cushions, of which the following is a specification.

This invention relates broadly to pneu matic cushions or pads, and it has for its primary object to provide a pad or cushion of this type adapted for home and hospital use and designed to serve not only as a cushion, but also as a receptacle for fluids, and provided with means whereby the fluids may be drained therefrom.

A further obj oct is to provide an inflatable pad which snall constitute, in addition to a supportinocushion upon which a patlent or invalid may rest with more than usual comfort, a device possessing some of the characteristics of a bed pan.

In oescribing the invention in detail, reference is herein had to the accompanying .1 m o '1 I drawings, in wine 1 Figure l is a top plan view of the invention; and" Figure 2 is a section on line 2-2, Fig. 1.

Referring to said drawings, 1 indicates a flat base of flexible material, preferably rubber, and superimposed upon said base are two inflatable tubular rings 2 and 3 having a substantially concentric disposition and possessing a form which 1s semr-cyl 1n drical in cross section. Said base, which is integral withsaid rings is made of such relatively heavier and inelastic material than the rings that, when the latter are fully inflated, the base retains its flat, or a substantially flat, form.

The inner ring 3 is substantially circular in form, while the outer ring 2 is of oblong oval form, being elongated and tapered in one direction to materially increase in said direction the relative width oi the space between said ings, said outer ring thus being made to conform to the part of the patients body which is to rest upon the cushion.

The bad or cushion described preferably has an outside diameter considerably in excess of that of the hospital cushions or pads which hitherto have been commonly employed; and, therefore, the inner ring 3 is provided as a support supplemental to that afforded by the ring 2.

The channel 4: formed between the rings 2 and 3. constitutes a receptacle for fluids which drain from the body of a patient resting upon the cushion, as does also the space enclosed by the inner ring 3. Drain age outlets of any suitable form, as nipples 6 adapted for having drain tubes 7 attached thereto, are provided in the base 1 at suitable points, as shown.

An inflation valve 8 is provided in the outer ring 2 at a suitable point, and a similar valve may also be provided in the ring 3, but it is preferred that a connecting passageway 9 be provided between said rings so that both may be simultaneously inflated by the use of the single valve 8.

Since the cushion has a flat base adapted to rest more or less closely throughout iipon the bed or mattress, it is manifest that the tendency. to shift, which is inherent in ordinary forms of cushions comprising tubes of cylindrical cross section, is largely obviated, thus in large measure contributing to the comfort of the patient. Furthermore, due to the provision of the receptacledike enclosures l and 5, soiling ofthe mattress is largely prevented.

What is claimed is l. A rubber pad comprising a flat base, a plurality of substantially concentric inflatable body-cushioning rings superimposed on said base and integral with the latter, said base being relatively inelastic, a radial communicating passageway between said rings, and drainage nipples iiXed in said base in the spaces enclosed by said rings.

2. A hospital pad comprising a flat base, two inflatable body cushioning rings superimposed on said base, the inner oi said rings being substantially circular in form and the outer of said rings having its major porion located concentrically with respect to said inner ring and being elongated and tapered in one direction whereby the relative width of the space between said rings is materially increased in said direction, and means adording drainage for the spaces enclosed by said rings.

In testimony whereof, I affix my signature in presence of two subscribing witnesses.

MAE DORRANCE.
